INCOMPLETE:

    1. PR for licensee re: `filterPackages`
    1. clean up license-check.js file
    1. add license info (and badge indicating verification?) to README
- License: Change from MIT to reflect actual content and dependencies: "(MIT AND Apache-2.0 AND CC-BY-SA-2.0 AND ISC AND LGPL-3.0-or-later AND X11 AND BSD-3-Clause AND BSD-2-Clause AND Unlicense)"
- License: Relicense ext-mathjax from Apache-2.0 to MIT per josegaert/ext-mathjax#6 ,
- License: Clarify in `@license` that `ext-server_moinsave.js` is MIT OR GPL-2.0-or-later per subsequent text
- License: Add script to check licenses
- License: Add `licenseInfo.json` file to clarify default license (MIT) and file and package-specific licenses
    - Per http://benalman.com/about/license/ , the GPL mentioned is GPL-2.0
    - Per https://jquery.org/license/ , jQuery is MIT
- Optimization: Remove unused `jquery-ui-1.8.custom.min.js` file
